Master N.R.L. Chandrasena represented Trinity at the All-Island Water Rocket competition organised by the Arthur C Clarke Institution for Modern Technologies (ACCIMT). He was supported by a group of Grade 10 students under the guidance given by Mr. Subash Dhanasekara who also attended the competition.
The water rocket works by using pressurized water to propel itself along. Water is filled to around half the capacity of a pressure vessel (Water bottle 1.5L), and air is pumped in using a foot cycle pump. The actual amount of water and air pressure needed depends on the distance in which the rocket is intended to travel.
The targeted distance for the rocket to land was 60m from its launch site. There were two rounds offered by the organisers and the rocket overshot the target at the both instances.
Seen in the pictures above are Master N.R.L Chandrasena (in school uniform), Grade 10 students and Mr Subash Dhanasekara (TIC) along with a student and a teacher from Hemamali Girls’ College Kandy, who were in the same group.
The College extends its gratitude to the Teacher-in-Charge Mr. Subash Dhanasekara for his continuous support and guidance throughout the competition.
